Oscillating De-Dusting Unit for Multi-Filter Vacuum Chamber Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuuming devices face issues with filter clogging, blowback, and structural complexity during filter de-dusting, particularly when using multiple filters, leading to performance loss and increased maintenance needs.
Innovation Solution
A de-dusting unit within the vacuum chamber uses oscillating movements generated by offset eccentrics to isolate and clean filters individually, allowing for multi-axis cleaning without vibrations, reducing component complexity and maintaining suction performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backflushing is used for filter de-dusting, then filter cleaning is achieved, but suction performance deteriorates due to blowback
Solution Approach 1:
The vacuuming device divides the filtration system into multiple independent filter units (first filter and second filter) that can be cleaned alternately. While one filter is being cleaned by backflushing, the other filter continues to provide filtration, preventing interruption of suction performance and eliminating blowback effects on the overall system.
Solution Approach 2:
The system implements periodic switching between filters for cleaning operations. The control unit alternates the backflushing operation between the first and second filters at predetermined intervals, ensuring that filtration capacity is maintained while both filters receive regular cleaning without compromising suction performance.
2Productivity
If two filters are used to reduce blowback, then suction performance is maintained, but device complexity increases
Solution Approach 1:
The system combines multiple filter units into a single integrated vacuuming device with a shared turbine and control unit. The first filter and second filter are arranged to work together in parallel, sharing common components such as the turbine, housing, and control system, which reduces overall complexity compared to having separate vacuuming devices for each filter.
Solution Approach 2:
The control unit is designed to perform multiple functions: it controls the turbine operation, manages the backflushing sequence for both filters, and coordinates the alternating cleaning cycle. This multi-functional control unit reduces the need for separate control systems for each filter, simplifying the overall device structure while maintaining dual-filter operation.
3Reliability
If unfiltered ambient air is used for flushing, then de-dusting is achieved, but components are damaged by contaminants
Solution Approach 1:
The system uses the vacuum chamber as an intermediary environment for the backflushing operation. During backflushing, the flushing air is introduced into the vacuum chamber where it mixes with the controlled atmosphere before contacting the turbine and other sensitive components. This intermediary space allows contaminant-laden flushing air to be contained and filtered by the operational filter, protecting components from direct exposure to contaminants.

AI summary
A de-dusting unit positionable in a vacuum chamber of a vacuuming device, where the vacuum chamber is delimited by a turbine, a first filter, and a second filter. The de-dusting unit includes a displacement module where the de-dusting unit is positionable within the vacuum chamber by the displacement module such that one of the first and second filters at a time is isolated from a suction flow and such that an oscillating movement of the de-dusting unit is transmitted to the isolated filter.
